- 自适应过滤法是根据一组给定的权数对时间数列的历史观察值进行加权平均计算一个预测值,然后根据预测误差调整权数以减少误差,这样反复进行直至找出一组“最佳”权数,使误差减少到最低限度,再利用最佳权数进行加权平均预测。-Adaptive filtering method is based on the number of a given set of rights to compute a weighted average of the predicted value of historical tim
SVM_regression_1001
- 一种可以择优选择参数的SVM拟合回归程序,通过for循环,可以调节参数,调出误差最小的参数设置。有时候,默认的参数也会有很不错的精度。-One can choose the best parameters of the SVM fitting regression procedures, through the for cycle, you can adjust the parameters, minimize the error of the parameter settings. Somet
knnmyself
- knn分类算法,可以自动将excel转换为mat,可以自行调整参数,第二列为标签-knn classification algorithm can automatically be converted to excel mat, you can adjust the parameters of their own, as a second label
mvstats
- 将ggplot2的作图结果合并为一个图,可以定义cols的值从而调整输出的结果(Combining the graphical results of ggplot2 into a graph defines the values of cols to adjust the output)
